WOOD-SPLITTING MACHINE.

v SPECIFICATION forming part of Letters P atent No. 508,020, datedNovember '7, 1893.

Application filed June 9,1892.

To all whom it may concern:

Be it known that 1, JAMES BURNETT IVEY, of Macon, county of Bibb, andState of Georgia, have invented a new and usefulImprovementinWood-SplittingMachines,ofwhich the following is aspecification.

This invention has reference to wood-splitting machines in which avertically-reciprocatin g power driven knife acts upon the blocks ofwood seated on an underlying supportingtable, and it relates to variousimprovements having special reference to cheapness, solidity ofconstruction and ease of adjustment.

In the accompanying drawings,-Figure 1 is an outline perspective view ofmyimproved machine. Fig. 2 is a front view of the same. Fig. 3 is avertical section from front to rear on the line 3-3 of Fig. 2. Fig. 4 isa diagram of the gearing by which the conveyer is driven from thesplitting machine.

In constructing my machine I mount on transverse timbers or sills A, twohorizontal overlying timbers or sills B, extending in a transversedirection, bolting them firmly together. On this base-frame, andshouldered and bolted strongly thereto, I erect the two posts orstandards D D, connected by a crossbar E, at the top. To thesestandards, near their upper ends, I bolt firmly the cast-iron main-frameF, of U-form. This frame is provided at its upper end'with half-bearingsand caps forming boxes G, to sustain the horizontal main-shaft H,whichis provided on one end with a driving-pulley I, at the'opposite end witha fly-wheel J, and at the middle with an eccentric K. The lower part ofthe mainframe is formed along its inner edges with vertical guides f, toreceive the intermediate sliding-block L, carrying at its lower end thesplitting knife M, which may be bolted thereto or cast integraltherewith, as preferred. It is also formed with integrallaterallyprojecting flanges it which constitute a base by which it isbolted against the posts or standards D. D.

The pitman N, lying in the center of the frame has its upper endprovided wither fashioned into a strap to encircle the eccentric, Whileits lower end is made of cylindrical form, sea ted in a bearinginthetopof the slide and secured by a transverse pivot-bolt 0. Under thisarrangement the rotation of the Sam... 436,116. (NomodeL) eccentricserves to carry the slide and its knife up and down with a positivemotion. As the slide and the driving-shaft are mounted in the frame castin one piece, the parts are held firmly in alignment and prevented fromworking out of their proper relations under any circumstances.

P represents a supporting-bed or table having on its sides supportingstuds 19, which are seated in inclined grooves in plates R, stronglybolted to the standards. The bed haslaterally-projecting ribs or flangesp which bear against the front faces of the supporting plates to keep itfrom tipping forward. The

bed may be changed in elevation at will by shifting its studs p, fromone pair of grooves to another. When released its studs slide downwardand backward in the grooves so that the'bed is seated firmly against thesustaining plates.

In connection with my machine I propose to use an endless conveyer orelevator, and for this purpose I mount on the main-shafta small pulleyQ, on which abelt S, is extended downward to a pulley T, on one end of ahorizontal shaft 15, the opposite end of which is sustained by astandard on one end of acastmetal bed-plate U, seated on plankingapplied to the main sills A. The shaft 25, is connected by miter gearswith the second horizontal shaft V, lying at right angles thereto andsustained by two standards on the base-plate. The shaft Vcarries abeveled pinion 'v, engaginga horizontal pinion W, revolving around apost on the base of the bed-plate. On this post there is mounted a yokeor frame X, which may be revolved horizontally, and carries on its underside a second horizontal shaft Y, receiving motion from the centralpinion W. On the top of the yoke there is mounted a horizontal shaft Z,carrying at the inner end a sprocket-wheel z, driven by a chain from asprocket-wheel 1 on the lower shaft.

Under the above arrangement motion is communicated constantly through acentral pinion to the top-shaft Z, while at the'same time the yokecontaining the shaft Z, is permitted to turn freely in its horizontalpath.

The shaft Z, carries, in addition to the driving pulley, two sprocketwheels .2, intended to drive two endless conveyer chains, which beingthus driven may be turned at any desired direction; or, in other words,extended in any desired direction from the machine while the drivingdevices continue their motion. I a

As regards this part of the invention the essential feature lies inimparting motion through a central pinion to the elevator driving shaftmounted in the turning yoke or frame so that the turning motion will notinterfere with the communication of power thereto.

Having thus described my invention, What I claim is- 1. In awood-splitting machine, the mainframe cast complete in one piece withthe shaft-bearing, the inner sideguides for the I knife carrying block,and the flanges to fit the sustaining standards. j

2. The combination in a wood-splitting machine of the two standards,theU-shaped 1 metal frame having the shaft-bearing andside 5 guidesintegral therewith, the shaft and its (20- l centric, the knife-head,the pitman and the vertically adjustable bed or anvil.

3. In a Wood splitting machine the combination with the parallel frameposts or standards, of the metal plates rigidly attached to therespective posts and having at their forward edges baokwardly anddownwardly inclined grooves or slots forming upwardly inelinedhook-shaped teeth, and the anvil having laterally projecting studsadapted to the grooves in the plates, and flanges below said studstoform bearings against the edges of the plates whereby the anvil isadapted to be adjusted vertically and to be supported without otherfastenings.

In testimony whereof I hereunto set my hand, this 18th day of February,1892,in the presence of two attestingxwitn'esses.
